• Spacer — An intermediate fastening part, metal spacer, or structural bushing used to maintain a constant, strictly determined distance between two elements, plates, or components of a gear mechanism or construction framework. This rigid component prevents mechanical deformations under tightening forces.
• Garment interlining — A technical workshop term used to describe a thin intermediate textile material, a lightweight interlining, or a stiffening cloth inserted between the garment's outer fabric and the actual lining, aiming to provide structure, stability, and an impeccable shape to collars, lapels, or shoulders. Historically, it denoted a small textile mat or decorative fabric placed in a foyer.
• Diaphragm girder — A secondary horizontal beam, rigid connecting piece, or structural stiffening element mounted transversally between two parallel main girders, aiming to maintain their distance constant, prevent their twisting or buckling, and uniformly distribute gravitational or dynamic loads. This element is essential in the construction of steel bridges, viaducts, and complex roof frameworks.
